To all whom it may concern.-

Be it known that I, JAcoB CHRISTIAN HAN- SEN-ELLEHAMMER, a subject of the King of Denmark,'residing at No. 147 Oresundsvej, Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in Controlling Devices for Engine Distributing-Valves, of which the following is a speci cation.

This invention refers to a simple and easily operated device for controlling the in and outlet mechanisms, such as slides, valves, or the like of steam engines, compressed air engines, hydraulic engines, or similar engines, for the purpose of regulating the speed of the engine or of reversing the en ine.

spending upon whether the cylinder or cylinders of the en ine in question are stationary, or rotary, t 1e said deviceconslsts of a rotatmg or stationary cam disk, against which the rods, or the like, which are connected with above mentioned members, press by means of rollers, or the like, and a circular, or a roximately circular, disk which is disposed eside said cam disk against whlch circular disk said rollers, or the like, also press,-and which is revolubly connected with Said cam disk at an eccentric point or is shi-ftable in its own plane in a direction transverse to the efiective direction of the cam, and which, furthermore, is connected with or actuated by a controlling member, by means of which it can becaused to oscillate through a certain angle around said point or can be shifted a certain distance to one side or the other, and can be held fast in these extreme positions as well as inthe central position and eventuall" inone pr more intermediate positions. 1 en the circular'disk isturn'ed or shifted more or less to one side, said rollers, or the like, will not touch the corresponding side or half of the cam disk which, e. corresponds to the forward movement 0 the engine, and the said members are consequently guided by the other. side or half ofthe camdisk;which otherside or halflc. corresponds to the reverse movement of te engine; When the circular disk is in its intermediate position, said 1ro1lers,-or the like, since they now press against a surface, purely revolving around a center line will not transmit any motive:

power to said members, and'tlie engine will consequently stop.

One form of construction of the aforesaid .11 for the crank shaft, and

control device is, by way of example, diagrammatically shown on the drawing, where the device is supposed to be used in connection with aro'tating engine with three sin le-action cylinders.

' igures-l to 4 represent an engine crank shaft in cross section, the control disks thereon and the adj listing-"mechanism therefor, 'theslide-valves andconnecting rods for the engine cylinders being indicated diagrammatically and the controlling devices being shown in different relative positions in these difl'erent figures.

Fig. 5 represents a side view of a portion of the engine crank shaft, an edge view of one of the control disks thereon, a section of the other disk thereon and an elevation of the-contact endof one of the slide rods.

Thes'ame reference numbers indicate corresponding parts in the dillerent figures.

The slides of the engine cylinders are indicated-as rectan les 1. The other rectangles 2 indicate the inlet openin' to the cylinders, not shown on'the drawing. The straight lines 3 indicate the slide rods, which are ac tuated by springs not shown in a direction toward the centerof the engine, and which, by means of roller 4 press against the cam disk 5.

The latter is secured to the stationary crank-shaft 6 of the engine, and, on its lower half or third-part, has two guidecurves 7 and 8, one to the left and the other to the ri ht of the stationar crank which is suppose to turn downwar On the upper part of the cam disk, the periphery of which may be circular; there is a turning-point 9 for the circular'disk 10, which has a recess periphery the rollers 4 also press. At a suitable point 12, the disk 10 is connected with therod 13 of an eccentric 14, which by means- 0f a'lever 15, can be turned and secured in various positions 20, 21 on a segment 16. a

An even transition for the rollers 4 from the disk 10, when the latter is swung out to theleft or tothe'rig'ht, to the curve 7 or 8 on the cam disk! can beiattained in various wa s. For instance, when the rollers 4' are cy ndrical asshown; the-'fdisk 10 can be given a somewhat greater diameter than the cam disk 5,

When the, eplgine revolves in the direction indicated by 'e' arrow 17," and the disk 10 assumes the shown extreme position to the against whose ri htpthg o [n t sh owii on" "Hi? gia wing "'epgrbxi mately at the dead peint, and the slide 1 Wlll the roller 4 will cqnpe {rein I on to the curve 7; amd' the l e wi '1 release the inlet opening.
